'eval' is a special built-in, and as such, cannot be usefully defined as
a function, because the shell rules for determining which command to
execute favor special built-ins over functions.

If anything, it would be nice if bash errored out on the attempt to
define a function named 'eval', rather than allowing it to succeed.

Yes, distinguishing between special and other built-ins would indeed be
nice.
